Educational interventions to reduce mental health stigma toward patients among healthcare professionals and trainees: a systematic review of randomised controlled trials.
Review in Social psychiatry and psychiatric epidemiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveMental health-related stigma among healthcare professionals and trainees remains a significant barrier to high-quality, person-centred care. Educational interventions are frequently proposed to reduce stigma; however, their effectiveness across professional groups and outcome domains remains uncertain. This review evaluated the effectiveness of educational interventions in reducing mental health stigma among healthcare professionals and trainees.
methodsA systematic review and meta-analysis were conducted. Searches of CENTRAL, PubMed, EMBASE, PsycINFO, and CINAHL were completed up to 1 July 2025. Randomised controlled trials evaluating educational interventions aimed at reducing stigma among healthcare professionals or trainees were included. Primary outcomes were changes in attitudes, knowledge, affective responses, and behaviourally related indicators. Certainty of evidence was appraised using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
resultsNineteen reports (including 21 studies) were included. Educational interventions significantly reduced explicit negative attitudes towards people with mental illness immediately post-intervention among both healthcare professionals and trainees (SMD = - 0.38; 95% CI [-0.53, - 0.23]). Intended behavioural outcomes improved among healthcare professionals (SMD = 0.57, 5% CI [0.03 to 1.12]), but not among students, and these effects were not maintained at follow-up. No significant improvements were observed in mental health knowledge or social distance, while evidence for affective outcomes remained inconclusive because of the small number of heterogeneous studies. The certainty of evidence ranged from very low to moderate.
conclusionEducational interventions may produce modest short-term reductions in explicit negative attitudes and improve intended behaviours among practising healthcare professionals. However, evidence for improvements in knowledge, affective responses, social distance, and sustained effects remains limited. Given the overall very low-to-moderate certainty of evidence, these findings should be interpreted cautiously. Future research should prioritise rigorously designed, theory-informed trials with standardised outcome measures and longer follow-up to determine how educational interventions can achieve durable reductions in mental health-related stigma.
